Holy crap yes! My brother has an akita who is the sweetest most awesome thing in the world. And he's 125 lbs at an athletic weight. To be honest, you can find over and undersized dogs in any breed. The standard for GSDs goes up to 75-ish lbs, but you can easily find bitches over 100 if you look in all the right (wrong) places. Even in well bred litters there are size variations outside the standard. Personally, I'd find the breed that fits you well based on their temperament and natural ability for what you want to do and look for an individual dog whose size conforms more to what you're looking for.
